# 知止 vs Know & Act

The clearest difference is in-app purchases: 知止 at none against Know & Act's 1. 知止 also leads on ads (none vs shown). Know & Act's advantage is update cadence (every 2 days vs monthly) and iOS requirement (13.0 vs 17.0). On price and device support there is nothing between them.

Both are free to download. Know & Act sells 1 one-off in-app purchase. 知止 asks for nothing beyond the download.

知止 ships an update monthly, Know & Act every 2 days. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
